Actually, I think that sums up the whole mess they have got themselves into.
Meghan wants to be a star in her own right. She isn't (very few of us are!) and rather than accept that has been blaming other people for the fact she doesn't have whatever is needed to become a 'star'.
She could have been a good supporting act in the RF, as she was in Suits. But she couldn't accept she would never be the 'star'.
It's a bit sad, really. She seems to be one of those people who will never be at peace with what they have, because someone else has more.
